Quote:I notice you said TV plossl, is it because of TV's legendary quality that helps absorb some of the defects of the plossl design, or because you just happened to have 2 of them?

Quote:Ed,Nice first light report! It looks like the The GT-100 and the BT-100 are the same. I am getting excellent results also and appreciate the fine optics in this rig. Looking forward to your reports as you push your binoscope to its highest limits.Gary
Quote: I'm also going to try a pair of Televue 19mm Widefields (the predecessor to the Panoptic) to see how they perform. They have a 62° AFOV.
It would also be interesting to try a cheaper brand of plossl and some of the smaller 1 1/4" widefields. Probably someone else can help us here.
Quote:appreciate your reply Ed! I look fwd. to hearing more when you get to test other ep's in your binoscope. how high do you think you can go for power, with them?
Quote:I love the looks of those things...they resemble a space ship hull, with the two primary lenses being the engines. the 45° oculars make it odd, but pull them out, it looks like a space ship! just imagine if that outer casing was mashined alu or something, instead of plastic!
Quote:Zach at Garrett told me that my binoscope was tested at 115x and collimation "was as good as it gets." I doubt I'll ever push them that high however. The real test will not be collimation, but CA and true, useable FOV.
